Inventor: UTSUNO HIDEO
IPC: E04H9/02
Filed: 1990-09-28
Abstract: PURPOSE:To select construction materials for a viscoelastic body easily without calculating and restrict vibration of a structure sufficiently while using the viscoelastic body of the same construction materials by using the viscoelastic body in which Young's modulus and dissipation factor can satisfy a prescribed condition at a working temperature. CONSTITUTION:A viscoelastic body 8a, in which Young force E and dissipation factor eta can satisfy conditions as shown in equations I and II at a working temperature, is used. That is, in a damping device 1a, according to the equation I, the dissipation factor of the device 1a is set to be maximized in a low fre quency area of about 10 - 100Hz. In other words, the high dissipation factor can be obtained in the low frequency area and a damping effect can be maxi mized, so that it is optimum for restricting low frequency vibration of a struc ture 2 such as a floor panel. Since the dissipation factor of the viscoelastic body 8a is more than 0.2 according to the equation II, the dissipation factor of the damping device 1a is set to be more than 0.05 in the low frequency area of about 10 - 100Hz. That is, a condition of the dissipation factor, where the vibration damping effect is exhibited noticeably, can be satisfied so that vibration of the structure 2 can be restricted sufficiently.

Abstract: PROBLEM TO BE SOLVED: To reduce the load of an assistant and to train a patient in a sitting attitude simply and safely by connecting the upper end of a column section to a handle section, and connecting a base section to the lower end of the column section. SOLUTION: This sitting attitude aiding tool 1 is installed so that both end sections of an arch-like member 21 are faced to a bed 5 side, a patient is seated on the edge (step section) of the bed 5 so that an waist is pinched between the linear portions 21a at both ends of the arch-like member 21, and a column section 3 is pinched by both knees or both thighs. The length of the column section 3 is adjusted so that the height of elbows becomes the height of a handle section 2, and the patient grasps the curve portion 21b of the arch-like member 21 with both hands. Since the abdomen of the patient is supported by a flat plate member 22 of the handle section 2, the patient is prevented from being overturned forward. The waist is pinched by both ends of the arch-like member 21, thus the patient can be prevented from being overturned in the lateral direction.  The column section 3 is pinched by both knees or both thighs, therefore the patient prevented from falling for the bed 5.

Abstract: PURPOSE:To prevent the generation of a rolling unevenness on a rolled stock and to shorten the time in rolling by detecting the temp. of a rolled stock and controlling the rotational speed of the roller for rolling based on the temp. of the rolled stock. CONSTITUTION:The rolled stock 3 which is transferred on a roller table 2 and bitten into the roller 1 for rolling is measured by a thermometer 20a at its temp. on each specified distance just before being bitten into the rolling roller 1. Whether this measured temp. is higher or lower compared with the temp. under ordinary rolling conditions is detected and if the temp. of the rolled stock 3 at specified position is found lower, the rolling speed is slowed down by a speed control means 21. If the temp. is found higher, the rolling speed is quickened, the heating temp./time of the rolled stock 3 is shortened and an energy saving can be executed.
